Some are cynical about the public school system because so many slackers and un-reformable bad boys are in it.
This idea is applied to our cities now. If they don’t want police, then let the place rot just as long no problems reach outside the zone. The US has already practiced this somewhat with inner-city ghettos, surprisingly, for many decades before any of this rioting. There are a lot of cops there, but what else has really been done to improve the place? The schools are garbage; there’s no opportunity.
